Premium 3D printed cups made with shiny silk PLA filament. This twisted wave design is unique & stylish for any desk. Note: Some of the color effects were the result of unique settings & cannot be reproduced. Not a defect, just a variant. 3D printed, very lightweight. All with exception of the rainbow are made with premium silk color transitioning PLA filament. Rotate the cups to see the colors transition. Does not require any special light or temperature to see the cool color effects. Due to the two tone filament colors, printed cups may have tiger streaks in some areas. Pens/pencils/props are not included & are for display purposes only. Printed & ready to ship (excluding Sunday & holidays based on USPS hours) We’ve worked hard to dial in our 3D printer so we can offer superior quality prints. With 3D printing some minor imperfections should be expected but it does not take away from the overall quality, function, & aesthetic of the product. Approx 0.8 mm thin but the protruding walls makes it feel sturdy. 4in tall 3in diameter, 2.25 inch inner diameter, & may be porous on bottom so not meant to hold liquids or heavy items. Is a bit heavier than our other cups but is still lightweight. Holds about 15 sharpies. Keep indoor & away from high heat. Listing is for a single pencil holder. We try our best to capture the true color of the product but colors may differ based on your screen resolution. We have various designs & colors so please see other listing. Please send a message if you have questions. What is PLA? Polylactic Acid (PLA) is different than most thermoplastic polymers in that it is derived from renewable resources like corn starch or sugar cane. Most plastics, by contrast, are derived from the distillation & polymerization of nonrenewable petroleum reserves. Plastics that are derived from biomass (e.g. PLA) are known as “bioplastics.” PLA is biodegradable under certain conditions such as high heat so it’s recommended to keep PLA printed products in door & away from extreme weather. Twisted Wave is a unique name personally assigned our shop.
